The benchmark for GPU ML/AI performance that I've been using the most recently is a CNN (convolution neural network) Python code contained in the NGC TensorFlow docker image. Hello, I am working with a Unet segmentation model for medical image analysis, and I would like to know how important are negative examples (with empty masks) for my model to learn that some images are 100% negatives. I am using Tensorflow as a backend to Keras and I am trying to understand how to bring in my labels for image segmentation training. The code I got works great for 2 output layers which has a binary image as label groundtruth. Not sure why would. If the tensorflow only store the memory necessary to the tunable parameteres, and if I have around 8 million, I supposed the ram required will be: Ram = 8. We show that convolutional networks by themselves, trained end-to-end, pixels-to-pixels, exceed the state-of-the-art in semantic segmentation.
